FAQ on characteristics and application of System Three's marine topcoat

Follow
  • How long before I can apply the WR-LPU over epoxy?

    Allow epoxy to cure at least 7 days at 70F or above before applying WR-LPU. Please see the Technical Data Sheet and the Paint Literature for more information on application. 

  • Shelf-life of System Three paints.

    System Three Silvertip Yacht Primer and WR-LPU Topcoat paints are guaranteed for 3 years from the date of manufacture. However, the shelf-life can be extended if stored well sealed above 50F. After 3 years, we recommend pre-testing a small sample prior to use. 

    Batch code: X(YEAR) XX(MONTH) XX(DAY) X (INTERNAL CODE).

  • How do I thin down or lower the viscosity of the WR-LPU Topcoat?

    The WR-LPU Topcoat may be thinned with clean deionized or distilled water at up to 25%. 

  • Custom colors for WR-LPU

    WR-LPU waterborne polyurethane topcoat comes in 12 standard colors.  We will match any color sample you send us for an upcharge with a minimum order of 1 gallon.  Small 4 oz. samples of all 12 colors are available for a nominal charge from the website.  These can be intermixed in any proportions to obtain the color you want in order to have it matched.

  • I want to paint a design on my wood/epoxy paddleboard but I do not know what kind of paint to use or when to paint.

    You can paint your design under or over the epoxy coating.  If it's underneath, ordinary house paint will do.  If it's on top of the resin, we would recommend our WR-LPU.
